In the Family-oriented Abstraction, Specification and Translation (FAST) domain engineering process for software production, a member of a software product family is automatically generated from a model expressed in a DSL. In practice, the time and skill needed to make the DSLs proved to be bottlenecks. FAST now relies on jargons, a kind of easy-to-make DSL(More)
The use of the electric power transmission and distribution system as a transmission medium for broadband communications is considered. It is found that there are three significant technical hurdles to be overcome before successful implementation of such systems can be accomplished. The first is the relatively high attenuation rate due to discontinuities(More)
Spectrum is presently one of the most valuable goods worldwide as the demand is permanently increasing and it can be traded only locally. The United States FCC has opened a portion of the spectrum from 3.1 GHz to 10.6 GHz, i.e. a bandwidth of 7.5 GHz, for unlicensed use with up to –41.25 dBm/MHz EIRP [1]. Numerous applications in communications and sensor(More)
This paper describes the experiences of a small team of domain experts in reengineering the configuration control software for the 5ESS® switch. The project consisted of three main phases: discovery, design, and deployment. During the discovery phase the team conducted a domain analysis of configuration control software. In the design phase the team created(More)
This is a project report from the Power Systems Engineering Research Center (PSERC). PSERC is a multi-university Center conducting research on challenges facing a restructuring electric power industry and educating the next generation of power engineers. More information about PSERC can be found at the Center's website: program. Our thanks is given to(More)
To date, there has not been a completely satisfactory comparison between theory and experiment for a ground system that is excited by a current with a submicrosecond rise time. This requires careful definitions of both the measured and calculated voltages because the electric field is no longer conservative and voltages become path dependent. An experiment(More)
Conclusions of epidemiological studies describing adverse health effects as a result of exposure to electromagnetic fields are not unanimous and often contradictory. It has been proposed that an explanation could be that high-frequency voltage transients [dirty electricity (DE)] which are superimposed on 50/60-Hz fields, but are generally not measured, are(More)
The frequency of the power system is small enough that the electric and magnetic fields in air can be considered as if they were independent [1]. Further, the distribution of each field can be calculated under the assumption that static theory applies. Given this, both the electric and magnetic fields can be calculated from a scalar potential.
